Working parents of children with behavioral problems: a study on the family-work interface

This study examines the process by which child behavioral problems are related to parents' well-being. We developed a family-work spillover model that was tested among 225 working parents. It was hypothesized that family-self conflict (FSC) mediates the relationship between child behavioral problems and parental strain, and that family-work conflict (FWC) mediates the relationship between parental strain and work engagement. Further, it was hypothesized that social support moderates the relationship between child behavioral problems and FSC. The results of (moderated) structural equation modeling supported the mediating role of FSC and FWC and the moderating role of social support. These findings suggest that the negative effects of raising a child with behavioral problems on parental well-being can be buffered by social support.     

Crossover of job demands and emotional exhaustion within teams: a longitudinal multilevel study

This study investigated the crossover of job demands and emotional exhaustion among team members and the moderating effect of cohesiveness and social support on this process. Participants were 310 employees of an employment agency in the Netherlands, working in one of 100 teams. Multilevel analysis using a longitudinal design did not reveal a main effect of crossover. However, consistent with the study's hypotheses, the results showed a moderating effect of team cohesiveness and social support. We detected crossover of job demands and emotional exhaustion across time from the group to individual team members only in teams characterized by high levels of cohesiveness and social support. Teams characterized by low levels of cohesiveness and social support showed no crossover of job demands and exhaustion. The findings demonstrate that team-level moderators play an important role in crossover processes. Moreover, social support and cohesiveness may not always be positive.     

The (mis)reporting of statistical results in psychology journals

In order to study the prevalence, nature (direction), and causes of reporting errors in psychology, we checked the consistency of reported test statistics, degrees of freedom, and p values in a random sample of high- and low-impact psychology journals. In a second study, we established the generality of reporting errors in a random sample of recent psychological articles. Our results, on the basis of 281 articles, indicate that around 18% of statistical results in the psychological literature are incorrectly reported. Inconsistencies were more common in low-impact journals than in high-impact journals. Moreover, around 15% of the articles contained at least one statistical conclusion that proved, upon recalculation, to be incorrect; that is, recalculation rendered the previously significant result insignificant, or vice versa. These errors were often in line with researchers’ expectations. We classified the most common errors and contacted authors to shed light on the origins of the errors.     

Development and validation of the job crafting scale

We developed and validated a scale to measure job crafting behavior in three separate studies conducted in The Netherlands (total N = 1181). Job crafting is defined as the self-initiated changes that employees make in their own job demands and job resources to attain and/or optimize their personal (work) goals. In Study 1 and 2 the Dutch job crafting scale (JCS) was developed and tested for its factor structure, reliability, and convergent validity. The criterion validity of the JCS was examined in Study 3. The results indicated that there are four independent job crafting dimensions, namely increasing social job resources, increasing structural job resources, increasing challenging job demands, and decreasing hindering job demands. These dimensions could be reliably measured with 21 items. The JCS shows convergent validity when correlated with the active constructs proactive personality (+), personal initiative (+), and the inactive construct cynicism (?). In addition, results indicated that self-reports of job crafting correlated positively with colleague-ratings of work engagement, employability, and performance — thus supporting the criterion validity of the JCS. Finally, self-rated job crafting behaviors correlated positively with peer-rated job crafting behaviors.     

Work engagement,performance, and active learning: The role of conscientiousness

The present study examines whether the relationship between work engagement and job performance is moderated by the extent to which individuals are inclined to work hard, careful, and goal-oriented. On the basis of the literature, it was hypothesized that conscientiousness strengthens the relationship between work engagement and supervisor ratings of task and contextual performance as well as active learning. The hypotheses were tested on a sample of 144 employees from several occupations. Results of moderated structural equation modeling supported the hypotheses. Work engagement was positively related to task performance, contextual performance, and active learning, particularly for employees high in conscientiousness.     

The Role of Socioeconomic Status in SAT-Grade Relationships and in College Admissions Decisions

This article examines the role of socioeconomic status (SES) in the relationships among college admissions-test scores, secondary school grades, and subsequent academic performance. Scores on the SAT (a test widely used in the admissions process in the United States), secondary school grades, college grades, and SES measures from 143,606 students at 110 colleges and universities were examined, and results of these analyses were compared with results obtained using a 41-school data set including scores from the prior version of the SAT and using University of California data from prior research on the role of SES. In all the data sets, the SAT showed incremental validity over secondary school grades in predicting subsequent academic performance, and this incremental relationship was not substantially affected by controlling for SES. The SES of enrolled students was very similar to that of specific schools' applicant pools, which suggests that the barrier to college for low-SES students in the United States is a lower rate of entering the college admissions process, rather than exclusion on the part of colleges.     

Anxiety-induced changes in movement behaviour during the execution of a complex whole-body task.

We investigated the impact of anxiety on movement behaviour during the execution of a complex perceptual-motor task. Masters' (1992) conscious processing hypothesis suggests that under pressure an inward focus of attention occurs, resulting in more conscious control of the movement execution of well-learned skills. The conscious processes interfere with automatic task execution hereby inducing performance decrements. Recent empirical support for the hypothesis has focused on the effects of pressure on end performance. It has not been tested so far whether the changes in performance are also accompanied by changes in movement execution that would be expected following Masters' hypothesis. In the current study we tested the effects of anxiety on climbing movements on a climbing wall. Two identical traverses at different heights on a climbing wall provided different anxiety conditions. In line with the conscious processing hypothesis we found that anxiety had a significant effect on participants' movement behaviour evidenced by increases in climbing time and the number of explorative movements (Experiments 1 and 2) and by longer grasping of the holds and slower movements (Experiment 2). These results provide additional support for the conscious processing hypothesis and insight into the relation between anxiety, performance, and movement behaviour.
